Isopycnal elevation (blue curve) and squared Morlet walet at 40 min period (orange curve) \(\pm 3\) h around respectively high/low water during neap tides of PROTEVS GIB20 field experiment. Red dots mark the peak detection of the Algorithm. The black dashed curve shows the sea level at Tarifa. Numbers on the right are the time (day hour:min of October, 2020) of high water. The vertical dotted lines frame the time interval scrutinized for detection.
